Life is hard. Then you die. Then they throw dirt in your face. Then the worms eat you. Be grateful it happens in that order.

The problem with the gene pool is that there's no lifeguard.

In the 20th century, we had a century where at the beginning of the century, most of the world was agricultural and industry was very primitive. At the end of that century, we had men in orbit, we had been to the moon, we had people with cell phones and colour televisions and the Internet and amazing medical technology of all kinds.

Understanding the laws of nature does not mean that we are immune to their operations.

What I wish is that people would look beyond the tribbles and see I've written some other books that I really would like people to notice. There's 'The Man Who Folded Himself,' there's 'The Martian Child,' which is about my son and the adoption. There's 'The War Against The Chtorr,' which is my magnum opus, my great epic story.

What's interesting about the shift from an industrial age to a technological age is that we keep inventing new media: movies, records, radio, television, the Internet, and now ebooks - and one of the things that's most interesting about the invention of a new medium is watching it reinvent itself as it penetrates the culture.

In the entire history of the human species, every tool we've invented has been to expand muscle power. All except one. The integrated circuit, the computer. That lets us use our brain power.

I had always been fascinated by the whole idea that Australia was this different ecology and that when rabbits and prickly pears and other things from Europe were introduced into Australia, they ran amok.

If you were a kid in 1955, you would pick up a copy of 'Popular Science' and it would say, 'This is the kind of car you're going to be driving in five years or in 20 years you'll be able to take a jet plane from New York to London in four hours,' or something like that. We actually got used to the idea that the future's going to be different.

Science fiction is a unique literature. Science fiction is the first literature that says, 'Tomorrow is going to be different than yesterday, it's going to be a lot different.'

'Who are we?' And to me that's the essential question that's always been in science fiction. A lot of science fiction stories are - at their very best - evocations of that question. When we look up at the night sky and wonder, 'Is there anyone else out there?' we're also asking who we are we in relation to them.

In the past, a great library was the result of librarians functioning as guardians of culture, tending and caring, selecting and recommending works that maintained and nurtured a cultural heritage.

Just as movies, radio, and television evolved into new forms over time, the ebook will also become something more than just a way to read books. It will become its own specific and unique way of creating and sharing experience.

Doesn't anybody ever want to talk about anything else besides 'Star Trek?' There were 79 episodes of the series; there were 55 different writers. I was only one of them.
